✓ In stock The South Mountain Supply 18915 is a white nylon triple-head door trim panel retainer for Chrysler vehicles. The triple-head design grips all three panel layers simultaneously — providing a secure, factory-quality fit that prevents door trim panels from rattling, pulling away, or cracking the mounting hole over time.

A triple-head retainer has three head tiers — a large bottom head that sits behind the door substrate, a middle tier that grips the door panel foam/cardboard, and a smaller top head that holds the trim panel's inner surface. This three-layer grip distributes load across the full panel stack, preventing any single layer from cracking or pulling through at the mounting hole. Why is this retainer white instead of black? Chrysler vehicles used white door trim retainers in the door panel cavities on many models. The white color is factory-specified for these applications and ensures the retainer blends with the white foam backing of the door trim panel, which is visible from the inside of the door cavity. Using a black retainer in this location is functionally identical, but white matches the OEM specification. How do I replace door trim panel retainers on a Chrysler vehicle? Use a trim removal tool to pry the door panel away from the door frame, starting at the bottom corners and working around the edges. As each retainer releases, work methodically to avoid bending the panel. Remove broken retainer bodies from both the panel and the door shell. Press new 18915 retainers into the panel holes before reinstalling, then press the panel onto the door frame until each retainer snaps into its corresponding door hole. What pack size should I order? The 18915 is available in packs of 50, 100, 200, and 300. For a single-door repair on a two-door Chrysler, a pack of 50 provides ample coverage. For a full four-door interior retainer replacement, a pack of 100 is recommended. Shops servicing Chrysler vehicles regularly should stock the 200 or 300 pack for maximum cost efficiency. Will old broken retainer pieces damage my door panel? Broken retainer fragments that remain in the door panel holes can prevent the new retainer from seating properly and cause the door panel to sit unevenly or rattle. Always use a pick or needle-nose pliers to clear any broken plastic fragments from the mounting holes in both the door panel and the door frame before installing new retainers.
